Allen & Overy (A&O) is boosting its New York litigation practice with the hire of Eugene Ingoglia from white-collar boutique Morvillo. Ingoglia joins the magic circle firm's 12-partner strong US investigations and litigation practice.

Before joining the boutique two years ago, Ingoglia was a federal prosecutor at the Southern District US Attorney's office, where he was a member of the Securities and Commodities Frauds Unit.

There, he led the investigation and prosecution in the so-called 'London Whale' case, prosecuting two executives for overvaluing complex securities, and he was on the prosecution team for the insider trading conviction of former SAC Capital portfolio manager Mathew Martoma.

At Morvillo, Ingoglia said he has represented companies and individuals in criminal cases and investigations brought by the government and regulators.

Ingoglia said he wasn't looking to leave the firm but found the opportunity to join A&O too compelling to pass up, noting several Southern District former prosecutors practice there. He said he was also attracted by the chance to represent companies and banks facing increasingly multinational investigations by regulators.

"You're seeing more of these multi-jurisdictional investigations," he said. "Those opportunities at A&O will be greater because of its international breadth."

Tim House, A&O's global head of litigation, said: "His experience is exactly what our financial institution and other clients are looking for in defending their interests in difficult and often high profile investigations, enforcement and criminal proceedings."
